I'm posting here because it seems that the CONTENTGROUP tag is not being read. This sometimes gets used in video game music to indicate the name of the game, or the console. I did a quick test: file tag and display. (CONTENTGROUP is displayed as Category in the Winamp media library.) Winamp treats the file as though it has none/empty string.

Do you think this could be looked into sometime? I use this for organization so it would be great to have it working

I can't promise timelines as I am in the middle of work related projects but I will get to it eventually.

I'm happy to announce that Opus 1.3 was just released. This major
release again brings quality improvements, new features, and bug fixes.
You can read all the details in this release demo page:https://people.xiph.org/~jm/opus/opus-1.3/

Changes since 1.2.x include:
- Improvements to the VAD and speech/music classification using an RNN
- Support for ambisonics coding using channel mapping families 2 and 3
- Improvements to stereo speech coding at low bitrate
- Using wideband encoding down to 9 kb/s
- Making it possible to use SILK down to bitrates around 5 kb/s
- Minor quality improvement on tones
- Enabling the spec fixes in RFC 8251 by default
- Security/hardening improvements

The only thing I can do right now is to provide just an updated version of the core opus library dll with no guarantees it will work on any platform earlier than Win10. I'm attaching it in a zip file, you'll have to manually copy and replace the file labeled "libopus-0.dll" in the "opusfile" folder in the Winamp install directory. No ambisonics support from in_bpopus.dll or enc_bpopus.dll yet. You can however benefit from the other performance and security improvements in the meantime. You'll know you've updated the file correctly if you open the plugin's [About] box and see the text "Opus Library version: libopus 1.3" at the bottom.

also, there is no such 64bit compiler at sourceforge or something like that?

If cost wasn't an issue I would get a Borland/Inprise C++ Builder Pro 32/64bit compiler.

So far, all of the free 64bit compilers I have found anywhere have overly large overhead/footprint that either get's packaged with the DLL/EXE or I have to distribute the overhead in separate dependency libraries which I need to avoid in certain situations. MinGW so far has been the biggest offender, but I have also tried others and I really don't like any of them enough to migrate to 64bit. Free stuff always has drawbacks that for me become non-starters for regular use.
